side-looking radar

[′sīd ¦lu̇k·iŋ ′rā·där]

(engineering)

A high-resolution airborne radar having antennas aimed to the right and left of the flight path; used to provide high-resolution strip maps with photographlike detail, to map unfriendly territory while flying along its perimeter, and to detect submarine snorkels against a background of sea clutter.

The Defense Advanced Research Projects Agency (DARPA) adopted the RGWS technology into the Pave Mover program, which put side-looking radar into the EF-111 aircraft to detect and track armored surface vehicles at long range while simultaneously guiding precision munitions to a target.

Side-looking radar (SLR) is an active microwave remote-sensing system: the imagery data are obtained by sending a radar pulse toward the ground, then receiving the reflected pulse wave after its interactions with the ground surface.

Side-looking radars (SLRs) have enjoyed continued success in mapping the earth's phenomena--including geology, vegetation, forestry, and topography--since the 1960s from aircraft, and from the 1970s from space platforms (Simonett 1970; Leberl 1976; Henderson and Lewis 1998).

Though forward-looking cameras have gravitated toward placement in the inside rearview mirror housing, and side-looking radar units are a natural for outside mirror housings, the question of where the front or rear units reside is still up in the air.

For example, the side-looking radar sensors used for the Blind Spot Information System (BLIS) and the forward-looking camera for the Lane-Keeping System are on watch even when there is no active warning provided to the driver.

In addition to the nose-mounted Elta EL/M-2022(V)3 surveillance radar, these aircraft have side-looking radars by the Swedish Space Corporation, in combination providing simultaneous tracking of surface vessels and mapping of oil spills.
